excel用VBA删除空行和空列

在Excel中删除空行和空列的方法有很多，下面的方法是用VBA代码来删除工作表指定区域中的空行和空列：

Option Explicit

Sub Delete_Empty_Rows()
Dim rnArea As Range
Dim lnLastRow As Long, i As Long, j As Long

Application.ScreenUpdating = False
lnLastRow = Selection.Rows.Count
Set rnArea = Selection

j = 0

For i = lnLastRow To 1 Step -1
If Application.CountA(rnArea.Rows(i)) = 0 Then
rnArea.Rows(i).Delete
j = j + 1
End If
Next i

rnArea.Resize(lnLastRow – j).Select

Application.ScreenUpdating = True
End Sub

Sub Delete_Empty_Columns()
Dim lnLastColumn As Long, i As Long, j As Long
Dim rnArea As Range

Application.ScreenUpdating = False
lnLastColumn = Selection.Columns.Count
Set rnArea = Selection

j = 0

For i = lnLastColumn To 1 Step -1
If Application.CountA(rnArea.Columns(i)) = 0 Then
rnArea.Columns(i).Delete
j = j + 1
End If
Next i

rnArea.Resize(, lnLastColumn – j).Select

Application.ScreenUpdating = False
End Sub

在运行代码前，先选择需要删除空行和空列的区域。如果要删除空行，则运行Delete_Empty_Rows()，指定区域中的空行将被删除。注意所谓空行是在指定区域中的，如果在指定区域内是空行，而在指定区域外不是空行，那么这些空行还是将会被删除。删除空列则运行Delete_Empty_Columns()。
